The JV terms call for EDC to earn a 70% interest by funding 100% of the next $58.3 million in project expenditures at Mariposa, and $8.0 million in project expenditures at the Peruvian concessions. Under the agreed work plan at Mariposa, the JV will further develop infrastructure over the next 18 months, including new roads and drill pads, and production-scale drilling will commence in late 2014.
